Nowadays, in Publish/Subscribe system, the number of subscriptions from customers can be large, the events happening in such a system are more frequent and the notification load is heavy. Combining with cloud computing that is becoming increasingly popular for scalability and availability it promises, called Sensor-Cloud, there are many approaches that improve data delivery issues in such scenario...
Smart phones such as the iPhone and Android phones have become increasingly popular in the recent market. Diverse applications can be implemented on smart phones since their performance has been improved. One of the promising application areas would be reading the emotional state of a human being and using it for communicating with the computer. In this paper, we present a robust facial expression...
In this paper, a new set of data signatures is derived to obtain better Vector Fusion 2D visualizations of a time series and periodic nD traffic data set as compared with previous work. The latter had used the entire Power Spectrum components for visualization purposes to produce 2D representations of each subset of the data. With the feasibility of obtaining a smaller representation of the data set...
The estimated national cost due to methamphetamine (meth) abuse is 23.4 billion each year. Current law enforcement of dealing with the meth abuse is by 'fire fighting' strategy, that is, to direct the enforcement to the location after the problem occurs. A better strategy is to develop a proactive predictive model based strategy. This study attempts to develop a model to predict the risk of meth production...
Contexts are appreciated as localized background knowledge for operations in knowledge management and applications. However, current context representations ignore the characters that contexts have different size, have multi-layer contextual dimensions, and contain both metadata and instances. In order to improve context representation, this paper proposes a novel context representation approach based...
In process control system, Process database is a main component for real-time, historical data processing. Recently, the concern on process database is increasing. From now, With process database, Historian or Memory DB with Relational Data model are mainly used. But, each has both advantages and disadvantages. Especially, on performance and flexibility, they have to complement each other. In this...
In this paper, propose a method for forest fire smoke detection in video based on digital image processing approach with static and dynamic characteristic analysis. The proposed method is composed of four steps. The first step is to detect the area of change in the current input frame against the background image. Second step is to locate regions of interest (ROIs) by connected component algorithm,...
This paper proposes separating confusion line method in Lab color space using color segmentation for protanopia and deuteranopia. It uses hue information, we segment regions that grouped by neighborhood pixels with similar color information. For this, we use region growing method, so we pick seed points that could be selected pixels, which is peaking at points in after applying the low pass filter...
